How do you bring ideas to life?

There’s a long answer and a short answer. The short answer is through hands-on development and design work, wherein I’ll take an idea and then try to build the most viable simple version of it as quickly as possible. Then I’ll see how people use it and either develop it further or switch over to another idea based on what I learn.

What inspires you?

Other startups and their dedication to building new experiences and implementing existing technologies in new ways. Also: thoughtful design, no matter the medium.

What is one mistake you’ve made, and what did you learn from it?

It’s crucial in a startup to constantly prioritize the most important projects and put anything on the backburner that doesn’t have a relatively high expected value. I’ve made the mistake of prioritizing things that shouldn’t have been prioritized, which caused resources to get tied up in projects that weren’t going to make a big enough difference for the things that mattered most at the time.

What is one business idea that you’re willing to give away to our readers?

Someone needs to build a really simple yet powerful personal contact organizer. It’s too hard to keep track of the people one knows professionally and personally, and it’s not easy to search one’s network when you need something.

What is one book and one tool that helps you bring ideas to life?

I’ve recently been reading The Innovator’s Dilemma which contains a trove of insight into how startups and larger corporations approach innovation differently.

I use surprisingly little software to work, but TextMate and Photoshop are my weapons of choice.

Who would you love to see interviewed on IdeaMensch?

David Karp, the founder of Tumblr.

What’s the best reason to start a company?

Because you want to breathe life into something that didn’t exist and then see it provide value to others at scale.
